PATENT LEOPOLD KATZENSTEIN, OF NEW YORK, N. Y.

METALLIC RING PACKING.

SPECIFICATION forming part of Letters Patent No. 595,811, dated December21, 1897.

Application filed March 3, 1897.

To all whom, it may concern.-

Beit known that I, LnoPoLD KATZENSTEIN, a resident of the city, county,and State of New York, have invented certain new and useful Improvementsin Metallic Ring Packing, of which the following is a specification.

My invention relates to metallic packing, and has for its object toproduce a packing adapted for use as a piston and valve rod packing, insituations where high pressures are employed, to take up extravibrations of the rod and which may be applied to and removed from therod and stuffing-box without disconnecting the said rod, thereby savingconsiderable time, labor, and expense.

My invention will be understood by referring to the accompanyingdrawings, forming part hereof, which show a packing embodying myinvention.

In the drawings, Figure l is a side View of the packing with itscooperating casing and stuffing-box in section. Fig. 2 is a sectionthrough the packing-rings, showing also the arrangement of the parts ofthe casing. Fig. 3 is a section on line 3 3 of Fig. 1 and shows also thesection-line 2 2 on which the section Fig. 2 is taken. Fig. 4 is a planview of one of the end rings of the packing. Fig. 5 is a section thereofon line 5 5 of Fig. 4. Fig. 6 is a plan view of one of the intermediaterings of the packing. Fig. 7 is a section on line '7 7 of Fig. 6. Fig. 8is a plan View of the expansion-ring, and Fig. 9 is a section on line 99 of Fig. 8.

In the drawings, A is a suitable stuffingbox provided with the usualgland B. Contained within this stuffing-box is a casing O. This casingcomprises two body-sections c c, which are of semicircular form and havetheir edges 0 c stepped and lapped. One of these sections is providedwith pins or screws 0 c. The cap of the casing, which forms partthereof, comprises two semicircular sections 0 0 which fit on thecasing-sections c c after the manner of the top of a box. Rings arecontained in the casing. In the present instance I have shown theserings as follows: I) b are the end rings each, as shown in Fig. 4,comprising two parts b 17 one or both of which parts may be pierced orapertured, as with an aperture h to receive and hold a pin or pins 0which passes through the rings of the pack- Serial No. 625,830. (Nomodel.)

ing, each of which rings is shown as pierced for the passage of the pinor pins, except the middle or expansion ring a, which is of sufficientsize to allow the pin to pass therethrough when it is in the positionshown in the figures. These rings 1) have curved faces 19 to allow thepacking to vibrate with the rod in the casing and may be held fromrotating by pins 19 set in the casing. The intermediate rings 01 areshown as comprised of three sections cl 01 d which sections are beveledon both edges 01 d and grooved at d to receive a suitable spring d andrecessed for the reception of sectional rings comprising segments ofBabbitt or other soft m etal d These sections 01 are placed loosely inthe ring d in such a manner as to break joints, as clearly shown at d dd. The rings 01 are so placed as to break joint with the joints of therings 19 and are put together edge to edge with their beveled sections dadjacent. Intervening between the rings at is an expansion-ring a, whichis shown in Fig. 8 as consisting of several sections a a a of triangularform, grooved at the rear for the reception of a spring a and fitting inthe angular space formed by the bevels d between the two rings. Thisexpansion-ring is also placed in such a fashion as to break joints withits adjacent rings d d, so that from end to end of the packing all thering-sections break joint with each other to prevent steam from leaking,and a very efficient packing is produced, the pins 0 which, however, maybe replaced by a number of similar pins, preventing the rings revolvingone upon the other when the piston-rod D reciprocates back and forththrough the packing. At the parts of the rings cl which are laidtogether the walls of the rings are prolonged inwardly to form flanges(1 in order to more securely hold the ring-sections d ,and the endrings 1) are flanged at b to receive the beveled ends d of the rings (1and press the same toward the rod.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-- 1. In a packing, the combination of sectional endrings 19, intermediate sectional rings 01 recessed for the reception ofsectional metal pieces 61 the rings cl being beveled at each end andrecessed peripherally, springs for holding the rings 01 firmly aroundthe piston-rod, a triangular spring expansion-rin g a interveningbetween the rings'cl d and a pin or pins for holding said rings inalinement, adjacent sectional rings breaking joints with each other fromend to end of the packing.

2. In a packing, the combination of inside conical flanged end rings 1),intermediate sectional rings cl recessed for the reception of segmentalpieces (1 the said rings d being beveled at one end to enter the flangedend rings 1) and at the other end to form a triangular groove, atriangular spring expansionring (i between the rings d, means forpreventing the rings from turning one on the other, the said ringsbreaking joints with each other from end to end of the packing.

3. In a packing, the combination of flanged end rings, intermediatesectional sprin g-rin gs beveled at one end to enter the flanged endrings and at the other end to form a V-shaped groove, the saidintermediate rings being recessed for the reception of segmental pieces(Z and provided with flanges (Z and a sectional spring-ring aintervening between the intermediate rings.
